Since I work for myself and don't go to an office everyday, I don't need to dress up unless I have a meeting. My daily go to "uniform" always revolves around dark jeans paired with a blouse or blazer. This has been working especially well since the weather is not yet warm enough for dresses. As you can see from these lovely ladies, it's a popular look. Of course, pairing it with a Birkin doesn't hurt.
